WebThe QT interval represents the time of ventricular activity including both depolarization and repolarization. It is measured from the beginning of the QRS complex to the end of the T wave. Normally, the QT interval is 0.36 to 0.44 seconds (9-11 boxes). The QT interval will vary with patient gender, age and heart rate. 2. PR interval. WebThe interval should be measured in the lead with the largest, widest P wave and the longest QRS duration.
